APPARATUS FOR HANDLING MAGNETIC MATERIALS.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed April 22, 1910. Serial No. 556,950:

citizen of. the United States, residing at Cleveland, in the county of Uuyahogaand State of Ohio. have in vented new and useful Improvements in Apparatus for Handling Magnetic Materials, of wl'lich the following is a specification.

My invention relates to means for ecopoinically and safely transporting magnetic materials. I

The object thereof is to combine one or more electro-m-agnets for picking up magnetic materials with one .or more suitable receptacles for transporting the said mate rials and with crane mechanism for hen dl'ing both the lifting magnet or magnets and the-receptacle or receptacles.

The principles of my invention may be embodied in various forms, but I have shown only a few forms thereof in the acco1npanying drawings, in which Figure l. is a side view of an end portion of a crane fitted with one form of my invenwherein the lifting magnet is adapted to dump the receptacles; Fig. 7, a side view of my invention adapted to the handling of.

plates, billets, rails, etc; Fig. 8, an end View thereof; Fig. 9, an end view of the invention shown in Figs. 7 and 8, to illustrate one method of piling sheets; and Fig. 10, a side View of my invention in connection with chargingmechanism for continuous heating furnaces. Referring first to F 1 and 2, I show in general the c1-ane.C,wli-icl1 may be stationary or traveling, as desired. The crane O has the trolleys T and at, running on separate traclrs'c and e on the parallelgirdei's g and g. The hoist ropes T, suspended from the widely-spaced hoisting drums T on the trolley Tare fixed to the beams T from which are suspended the hooks T capable of being,

inserted in the end openings of thereceptaclcs R, shown, in this instance, to be chargj ing boxes for furnaces. To the ropes t,

. suspended from the. hoisting drum. 2 of the trolhiy t, is attached the lifting magnet M,

The girders are placed between the girders g, the tracks 0 are below the tracks 0 and the drums T are widely spaced apart, so that the trolley 25 can pass under the trolley T, or the trolley T can pass over the trolley t, with the trolley 15 betwetn the ropes T. C(mseqnently, the magnet M maypick upa load of magnetic material in the position shown in full. lines on Fig. 1 and lift and convey the same in a well known manner to the. position shown in dotted lines, where the magnet M is directly over some of the receptacles lit. lV hen the loaded magnet in this position is demagnetized, it drops its load into the said receptacles. The magnet then picks up another load of magnetic material and deposits the same in the receptacles R. The magnet repeats these operations until the receptacles are sutficiently loaded, when they are conveyed by the crane or trolley or both to some predetermined place of deposit where they are dumped or unloaded.

In. Figs. 3 and at, there are two parallel girders y on which the unain trolley T runs. On this trolley are fixed the two parallel tracks T, on which the trolley t runs, the tracks T being below the tracks 0 on which the trolley T runs and between the 'ropes 'l" of the trolley T so' that either of the trolleys maypass the other and the mag net M may be lifted and brought into V61" tical alinement with the receptacle S or I), to whose endsthe ropes T are connected. The tracks T are extended enough at one or both ends of the trolley T, as shown in.

dotted lines, Fig. 3,-to allow the trolley 25 to be moved so that the magnet M may be lowered past the receptacle S or b. The operation of this second form of my invention is not substai'itially di'lferent from thatshown in Figs. 1 and 2.- Thebucket S is all inclosed except the top. The bucket]; has one end also open and is provided with the Wheels W. 'lhis-bueket will-hefurther described in connection with Fig. 6.

In Fig. 5, the trolleys T and 15 travel on ,thesamc track 0 laid on the girders 9 (only ,one shown) of thehridge B, capable of travel'-' onthe rails 0*. From the trolley is sus pended the open-hearth charging device T which has at its lower endthe armor menher T rotatable on the part T .in a horizontal plane and carrying at its outer end the charging box D. The trolley t carries the lifting magnet M as in the other'forms of my invention. The receptacle-D can, by

movement of the trolley T and the proper rotation of the arm T be brought over or near the railroad car E, or a pile of stock. The magnet is lowered onto the material in the car or pile and when energized, lifted with its load above the box D, whereupon the box may be swung under the magnet, or the latter brought over the box D so that,'

when the magnet is deenergized, the box will catch the material released fromthe magnet. This operation may be repeated I until the box Dis filled, after which the arm to be plaoed,

. parts marke'dT", T, and T, as they are well known. r

In Fig. 6, I have shown the trolleys T and t as in,.Figs.' 3 and 4;, where the trolley t travels 'e'n tracks on the .trolley T. The receptacle bis connected at its ends tothe ropes '1 pendent from -the main trolley T- 'and is rotatable on a. horizontal'axis, as at b. A front view-of the receptacle 6 is shown on Fig. 4. Normally the receptacle b hangs, as shown in dotted lines shown at the left-hand end of Fig. 6,'witl1 the bottom 5 and the end I) inclined to the vertical. The bottom b is provided with thewheelswv so that when tilted down as shown in'jfull lines on Fig. 6, it maybe run-on the platform K to'the furnace F, into which the materials in the receptacle-Z) may be charged'in any desired manner. At the left-hand end of Fig.6 1- show the magnet M and therecepe tacle 6 arranged so that the magnet may:

remove materlal from the car E and drop it into the receptacle. In the middle; of 6, I show the magnet M operating'o'n the angle-iron a at the top of the back 6'' sons to dump the receptacle by causing the same to-tilt on its axis b until the outer end of the bottom is sufiiciently below the inner end to cause the materials ip t-he receptacle to slide out. In full lines on Figyfi, I show the magnet M on the angle a, by which the receptacle be has been tilted by magnetic.

action so that the wheels W-rest on the platform K. The magnet M may remain deenergized and caused to engage ,tijnder the angle a oi othersuitable part orllprg' ctipn on the receptacle to cause the latter 0 tilt or, dump its load; I do not limit myself to angle-irons as various other shapes and de vices will answer the purpose intended.

In Figs. 7, 8, and 9, I show two pairs of' parallel irders g g and g g as in Figs. 1 and 2. l he rope t of the trolley t supp orts the beam 1)? from'which any required numj;

'ber of magnets M are suspended. On "the rails 0 I have two trolleys Teach carrying at the lower end of its ro es T a beam T, connected to the ropes T y the readily disengageable hooks h. .The parts are arrangedas in Figs. 1 and 2 so thatt-he magnets lif with their load of plates 7) or other mate rials may pass between the ropes T',which are at opposite ends of the beams T. I show the magnets M in Figs]? and 8 transferring a plate from one of the cars E to the piles of plates which have been previously transferred from the car so as to be supported on the beams T which constitute what I call a sling. ,The beams can be brought to the prope position to support the load. 4

In Fig. 9, I show three piles of plates 32 superposed, adjacent piles being held separated'by the spacers 1:,- which are higher than the vertical width ofthe beams T.

k on thebeams T, which, may then be removed from beneath the pile. Insome cases the beams may be swung from beneath the pile which they have deposited without disconnecting the hook it.

on Figs.v 7, 8, and 9, except that I provide ;1'0( In F ig. 10, the parts are substantially as the continuous heating furnace F having in front thereof the pusher P arranged to push a series of billets I from the sling. onto the platform or track K which leads to the I furnace F The beams T have thereon the cross-supports'T", on which the magnethl deposited the billets I. After the sling is loaded with billets arra-n ed in a sin le hori zontal row, the trolley. conveys -t e sling to the right and lowers the same to theposition shown in. dotted lines where'the billets are in line with the pusher and the top of 'the'billet supports T" are flush 'w1th the track K. Those acquaintedwith furnace charging devices will understand how the furnace is regularly charged without further explanation.

'I' do not'limit myself to any form one.

rece tacle any device on which material may 0 deposited for transporting it from one place to another. 1

I claim- 1. The combination of two hoisting mechanisms, a receptacle carried by -one of the said mechanisms, and a lifting ma et carried by'the other of the said mec amsms, one of the said mechanisms being movable "ceptacle, as I intend to cover'by the word horizontally as a Whole so that the magnet and receptacle may be in such relative positions as to permit the magnet to deliver its load to the receptacle.

2. The combination of two hoisting mechanisms, a receptaclecarried by one of the said mechanisms, and a lifting magnet carried by the other of the said'mechanisms, one of the said mechanisms being movable horizontally as a Whole so that the magnet and the receptacle may be in vertical ahne ment with the magnet above the receptacle. The combination of a traveling bridge,

two hoisting mechanisms carried thereby,

one being movable horizontally, a receptacle carriedby one hoisting mechanism, a lifting magnet carried by the other hoisting mechanism, tracks for the hoisting mechanisms, and suspensory devices for the receptacle and magnet so arranged and constructed that the magnet may be over the receptacle.

4. The combination of two hoisting mechanisms, hoisting ropes suspended therefrom,

a receptacle connected to the hoisting ropes of one mechanism, a hftmg'magnet 0011- neeted to the hoisting ropes of the other l'ioisting mechanism, and tracks for the latter hoisting mechanism arranged between the hoisting ropes of the other hoisting mechanism, whereby themagnet and the receptacle may be brought into vertical alincment with the magnet over the receptacle.

- 5. The-combination of a crane, a recep tacle carried thereby, a hoisting mechanism also carried thereby, a lifting magnet carried by the hoisting mechanism, supports for the receptacle arranged to permit the hoisting mechanism as a Whole, and with it the magnet to move horizontally above the receptacle and into vertical alinement therewith.

G. The combination of a trolley, a receptaclecarried thereby, a second trolley having travel on the first trolley, a hoisting mechanism on the second trolley, a lifting magnet carried by "the said hoisting mechanism, and supports'for the receptacle arranged to permit the magnet and the receptacle to come into vertical aline'ment with the magnetover the receptacle.

7. The combination of a bridge, a trolley havingtravel thereon, a second'trolley having travel on the first trolley, a hoisting mechanism on each trolley, a receptacle carried by the hoisting mechanism of the first trolley, and a lifting magnet carried by the hoisting mechanismof the second trolley, the second trolley having travel so-thatthe magnet may be moved into and out of yertical alinement with the receptacle.

8. The combinatiombf a tilting receptacle and a hoisting mechanism. having relative horizontal travel, a lifting magnet connected,

to the hoisting mechanism, means whereby the magnet and receptacle can be brought into vertical alinement with the magnet over the receptacle, and means on the receptacle with which the-magnet. may be engaged and by which engagement the magnet may tilt the, receptacle.

9. The combination of a llOlStlllL' mechanism, a lifting magnet carried thereby, and' horizontally on the frame of the other.

12. The combination of a hoisting mechanism, a second hoistinmechanism supported on the frame 0 the first hoisting mechanism, a load carried by each hoisting mechanism. and means'arranged to bring the load on the second hoisting mechanism 'di rectly over the load on the first hoisting mechanism.
